Life 2.0; A new generation of scientific mavericks is not content to merely tinker with life's genetic code. They want to rewrite it from scratch.(Viewpoint essay)
Byline: Lee Silver (Silver is professor of molecular biology at Princeton University. He is the author of "Challenging Nature." He has no financial ties with any biotech firm.)
It last happened about 3.6 billion years ago. a tiny living cell emerged from the dust of the Earth. It replicated itself, and its progeny replicated themselves, and so on, with genetic twists and turns down through billions of generations. Today every living organism--every person, plant, animal and microbe--can trace its heritage back to that first cell.
